limits

The Compute and Block Storage APIs have resource usage limits.

Compute v2, Block Storage v1

Show compute and block storage limits

openstack limits show
    [--sort-column SORT_COLUMN]
    [--sort-ascending | --sort-descending]
    (--absolute | --rate)
    [--reserved]
    [--project <project>]
    [--domain <domain>]

--sort-column SORT_COLUMN

specify the column(s) to sort the data (columns specified first have a priority, non-existing columns are ignored), can be repeated

--sort-ascending

sort the column(s) in ascending order

--sort-descending

sort the column(s) in descending order

--absolute

Show absolute limits

--rate

Show rate limits. This is not supported by the compute service since the 12.0.0 (Liberty) release and is only supported by the block storage service when the rate-limiting middleware is enabled. It is therefore a no-op in most deployments.

--reserved

Include reservations count (only valid with –absolute)

--project <project>

Show limits for a specific project (name or ID) (only valid with –absolute)

--domain <domain>

Domain the project belongs to (name or ID) (only valid with –absolute)
